Hi, I’m not that familiar with this type of forum, but on some others they have an option where you can choose different themes.
For example on the Raspberry Pi forum I like to use ‘prosilver’.
Is it possible change the theme on this forum somehow? I find it pretty bright and not nice to use at night, and a darker theme would be very nice. 
Until then, the following filters in my adblocker take the edge off the brightness

Thanks for sharing, works great on ublock origin. much easier on the eyes. 
Just want to say thanks to the forum admin/monderator for adding the dark theme
Funny timing, someone just randomly suggested it on Discord earlier and I was like why not! You’re very welcome!
